    Notes: Abstract We report a patient with right hemiparkinsonism following haemorrhage in the left substantia nigra. The hemiparkinsonism responded to treatment with trihexyphenidyl hydrochloride and deteriorated after temporary discontinuation of the drug. Single photon emission computed tomography using technetium 99md, 1-hexamethylpropyleneamine oxide showed reduced uptake in the left putamen, globus pallidus and thalamus.

    Notes: Abstract The cerebellum has anatomical connections to the cerebral cortex, through which it can affect language function. To study these connections, we investigated patients with chronic Broca's aphasia using MRI and single-photon emission computed tomography (SPECT). We selected 15 such patients (9 male, 6 female, aged 17–64 years, mean age 56 years) from 30 chronically aphasic patients. Using the results of SPECT, we divided them into patients with (group 1) and without (group 2) crossed cerebellar diaschisis (CCD). We compared the language function of the two groups. Patients in group 1 showed classical Broca's aphasia, while patients in group 2 showed mainly word-finding difficulty. Patients with CCD hat infarcts involving the lower part of the frontal gyrus but patients without CCD did not, which suggests that this region may have functional and anatomical connections with the cerebellum. Our findings support the notion that the cerebellum contributes to language.

The hemiparkinsonism responded to treatment with trihexyphenidyl hydrochloride and deteriorated after temporary discontinuation of the drug. Single photon emission computed tomography using technetium 99m d, l-hexamethylpropyleneamine oxide showed reduced uptake in the left putamen, globus pallidus and thalamus.

    Notes: Abstract Primary progressive aphasia (PPA) presents with aphasia, with or without other minor cognitive dysfunction. We report five patients with PPA to show the correlation between their clinical signs and imaging findings. The patients can be divided into those with nonfluent (group 1) and those with fluent (group 2) aphasia. The characteristic speech impairment was bradylalia in group 1 and word amnesia in group 2. Impairment of comprehension was common but mild in both groups. On MRI, patients in group 1 showed predominantly left frontal and perisylvian atrophy with reduced uptake in the same region on single photon emission computed tomography (SPECT) using technetium-99m hexamethyl propyleneamine oxime (99mTc HMPAO). Patients in group 2 showed left temporal atrophy involving the superior, middle and inferior temporal gyri, hippocampus and parahippocampal gyrus on MRI and reduced uptake in the same region on SPECT. These findings correlated well with the functional anatomy of speech impairment.
